Other objects of the invention are to simplify and improve theconstruction and operation of this class of stoves. I

With these and other ends in view, which y a 5 will readily appear asthe nature of the invention is better understood, thesame consists 5 1nthe improved constructlon and novel ar-j rangement and combination ofparts, which will be hereinafter fully described, and par- '0 ticularlypointed out in the claim.

ing, which has been shown as being of cylii 1 drical form, said casingbeing connected at its upper and lower ends with the top plate 11 andthe base-plate 12 said top'and base plates being connected in theordinary manner'by rods 13 or by other suitable means.-

i The ash-pit 16-iscomposed of an independent casing, preferably ofcast-iron, having legs 17 whereby it is supported upon andele- 6 vatedabove the base-plate 12 of the stove. The fire-pit is spaced from thestove-casing 10 at its sides and rear end. Its front end is connectedwith an aperture in the frontwall of the stove-casing, where a door 18is provided to afford access, to the interior of the ash-p it, said doorbeingprovided with a draftinlet capable of regulation, as by slides 19of ordinary construction. r The top of the casting, which constitutesthe ash-pit, has an opening surrounded by an annular flange 9, whichlatter affords a seat for the fire-pot 14, which is flared upwardly andprovided'at its upper edge with a flange 8, that circuinferentially engaes the interior of the stove-casing, except at t e front, where a recess15 is provided for the downward passage ofsmoke and other products ofcom-. bustion. A grate 20 'is' supported in any suitable manner in thebottom of the fire-pot. 8 5 At the back of the stove-casing there is avertical flue 21, which extends the entire height of the stove-casing,of which it may be regarded as forming a part. This flue may be formedexteriorly upon-the casing, as in ,Figs. 1,2, and 3, or interiorly uponthe casing, as in Fig. 5, or said flue may be partinside and partoutside of the casing, as shown in Fig. 6. It is also to be understoodthat this flue may be constructed in any approved 9 5 and convenientmanner. At its lower end the flue 21 communicates, through an opening22, with the interior of the stove-casing adja-' cent to the base-plate12. The upper end of the flue 21 communicates with theexit-flue ICO 23,which latter also communicates with the interior of the stove-casingthrough an aperture 25 in the top plate 11. A damper 24 isprovided,'whereby the aperture 25 and the upper extremity of the flue 21may be alter- I05 nately obstructed. s

Fuel may be supplied to the fire -pot through a feed-door 27 upon thefront part of the casing or through an opening in the top plate 11, forwhich a cover 28 is provided. An inclined deflector 26 is secured uponthe inside of the casing beneath the feed-door .sired to check thecombustion, admission of air from the outside through the flue 29 beinggoverned by a valve 30.

Access to the space between the bottom of the ash-pit and the base-plate12 may behad for the purpose of cleaning said space when .necessarythrough an aperture in thestovecasing, for which a door or sl1de 31 18provided.

Baffle-plates 32 and 33 are disposed betweenthe fire-pot 14 and ash-pitcasing 16 and the interior of the stove-casing 10, said baffle-platesbeing extended from the rim or flange 8 of the fire-pot downwardly asfar as the bottom of the ash-pit and said deflectors being disposedabout midway between the outlet of the fire-pot and the outlet 22, whichconnects the stove-casing with the flue 21,-the object of saidbaffle-plates being to compel the products of combustion to traverse thespace between the bottom of the ash-pit. and the base-plate 12.

The stove can be readily adapted for burning various kinds of fuel, and,if desired, a magazine to hold a supply of fuel may be used, asindicated at in Fig. 1 of the drawings, supporting-hooks 34 for suchmagazine beingarranged upon the under side of the top plate 11 of thestove.

From the foregoing description taken in connection with the drawinghereto annexed, the operation and advantages of this invention will bereadily understood. When the fire is first started in the stove, thedamper 24 will be placed in position to obstruct the flue 21, permittingthe interior of the stove to communicate with the exit flue through theaperture 24. When the fire has gained headway, the damper 24 is turnedto the position shown in Fig. 1 of the drawings and obstructing theaperture 24 and the products of combustion will thus be com-, pelled topass from the fire-pot through the recess or opening 15 in a downwarddirection between the stove-casing and the sides of the ash-pit, beneaththe bottom of the latter,

and through the aperture 22 and vertical flue 21 to the exit-flue. Whileit is obvious that heat is radiated from the entire stove-casing, itwill be specially noted that the products of combustion almostimmediately after leaving the fire-pot and in a highly-heated orincandescent condition will be compelled to pass through the spacebetween the bottom of the ash-pit and the base-plate of the stove, whichlatter will thus be highly heated and caused to radiate heat in adownward. direction in accordance with the purposes of the invention.

The principal advantages of this improved stove are to be found in itsextreme simplicity, the castings constituting the fire-pot and theash-pit being readily applicable to the simplest kind of sheet-metalstove construction. Economy in construction is thus i11- sured, whileeconomy in the consumption of fuel obviously results from the fact thatthe heat is radiated mainly in the direction where it most is needed.

Having thus described the invention, what is claimed is In aheating-stove, a casing, top and bottom plates connected therewith, anash-pit I casing supported upon and elevated above the bottom plate,said ash-pit casing being connected with the front of the stove-casingand spaced from the latter at its sides and rear end, a fire-potsupported upon the ashpit and having at its upper end a rim contactingwith the stove-casing and provided with a notch or recess for thedownward passage of products of combustion, a flue or passage connectingthe lower end of the stovecasing with a point of exit, and baflie-platesdisposed between the stove-casing and the side walls of the fire-pot andthe ash-pit casing said baffle-plates extending from the rim of thefire-pot downward to the level of the bottom of the ash-pit, and saidbaflle-plates being also disposed between the notch in the rim of thefire-pot and the opening connecting the lower part of the stove-casingwith the flue leading to the exit-flue.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
